Summer is high season, with a packed events calendar and daytime temperatures averaging in the mid-70s from June through September. Crowds start to form at the city’s many museums, and airline ticket prices double.
Because of the city’s place in the business world, fall can bring hordes of businessmen who fly in from all over the world for stops at the Frankfurt Stock Exchange, financial institutions, or trade shows and conventions. Although this is an exciting time in the city, hotel prices can spike. Travelers would be smart to check the exhibition schedule ahead of time and book well in advance.
The low season starts right after Christmas and continues into March, with temps starting in the mid-30s and rising into the mid-50s by the start of spring. Warm, weatherproof clothes are a must this time of year, since there’s a good chance of snow and gusty winds.
The shoulder season starts in spring (April to May) and carries daytime highs in the 60s. Travelers can look forward to fewer crowds and lower prices.
